Solution

The correct option is B Epitope
  • An epitope, also known as an antigenic determinant.
  • It is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells.
  • For example, the epitope is the specific piece of the antigen to which an antibody binds.
  • The part of an antibody that binds to the epitope is called a paratope. Hence, Epitope is part of antigen.
So, the correct answer is 'Epitope'.
